well, the thing is, right now it wouldn't work with any operating system
just because of the whole way the mouse handling is programmed (many devices controlling the same cursor, aka, all are one)
it's the same problem with those nifty looking multi-touch displays of which there are videos all over the web
what most people don't see is, that this is the exact same problem
you wont see these used on your off-the-mill computer running whatever-operating-system that got ANY marketshare in the next say.. 5 to 10 years.
it's just not feasible to re-implement the whole concept of how to interact with an interface from ground up.
sad but true.
just give it 1 minute of thought
think of any program you're using right now, ANYTHING, that could be effectively used with 2 pointing devices (2 independent mice, multitouch).
might be just me, but i can't think of any ;-)
it's a nice problem to work on tho
i just don't see it happening anywhere outside academic institutions or companies able to afford such an investment (custom programs, custom hardware, for stuff that is already there for single-pointer devices)
